Answer:
When the magma, a molten rock flows as lava at the planet's surface, the surface gets cooled after a long, this whole process cause formation of some kinds of minerals on that surface.
Explanation:
Magma and Lava both are types of molten rock. The underground molten rock is called magma while the exploded molten rock on surface is known as lava. When these rocks cools down they get solidified and form crystal rock structure. Cooled magma is called plutonic igneous rock and cooled lava is called volcanic igneous rock. These rock crystals are of different sizes and consist several minerals such as Silicon(Si), Sodium (Na), Potassium (K), Aluminium (Al), Iron(Fe), Magnesium(Mg), Calcium(Ca). Some rocks that forms minerals consist high amount of iron. The amount of minerals and elements in every rock can very depending on shape and size.
Because if the axis wasn't tilted the sun wouldn't shine on the top of the earth.
Answer:
The distribution of large-scale ecosystems (biomes) is determined by climate. Latitude, air pressure and winds are important factors that determine the climate of a place.
Answer:
The EMF of the batteries connect in series in the circuit is 12 V.
Explanation:
Given;
two batteries, each is 6 V
The EMF of the batteries connect in series in the circuit is calculated as sum of the voltage of the two batteries since they are connected in series.
EMF = V₁ + V₂
EMF = 6V + 6V
EMF = 12 V
Therefore, the EMF of the batteries connect in series in the circuit is 12 V.
